BRC Mesh Reinforcing

Fabric Reinforcing MeshWith more than 50 years experience in the production of reinforcing mesh, BRC Mesh is a leading supplier of customised reinforcing products to most industry sectors. Reinforcing mesh has a wide variety of uses, ranging from the ordinary household to heavy industry.

In many construction applications such as reinforcing, a welded mesh fabric is preferred to rebar, particularly if Ferro-Fabrik is used. Ferro-Fabrik is a top quality product conforming to SANS 1024:2012. It has greater features and strengths than rebar (minimum 485Mpa) allowing a material saving of ±8%, and allows for time saving when fixing on site.

Features of Reinforcing Mesh

• The unique deformed wire pattern (curry pattern) offers superior bonding, improved stress distribution and crack-width control.

• Ferro-Fabrik is available in a wide range of diameters and apertures. The product can be bent to shape as required.

• Manufactured from hard drawn wire (smooth) and cold rolled wire (deformed).

• All intersections are resistant-welded thereby not reducing the tensile strength of the wires.

• Mesh has an average shear strength equal to 80% of the wire strength.

• The wire used has physical properties which are rigidly controlled to produce mesh with maximum weld strength combined with ductility.

• Appropriate customer solutions

• Specifications allow for cold rolled wire with a minimum ultimate tensile strength of 510Mpa and a high resistance to fatigue.

• Mesh is available in black and galvanised (pre-galvanised) sheets or rolls.

Quality Control

Reinforcing mesh is produced to highest quality standards and complies to ISO9001:2008. Thorough testing, of wire strength, welds and aperture sizes, is continuously performed at all stages of the manufactur-ing process. Final inspections ensure that highest standards are maintained.

Standard Sizes

Reinforcing mesh is available in rolls (60m x 2,4m), and sheets (6m x 2,4m) manufactured according to standard sizes. Wire diameter varies from 3,55mm to 12mm. Mesh aperture can be as small as 100mm x 100mm.

Special Mesh

Specialised machinery is used to produce weldmesh with non-standard aperture sizes. The spacing of wires in either direction is variable between 13mm and 150mm.

Customised mesh is available on request according to specifications provided. Customers and design engineers should contact BRC Mesh before embarking on the design of such mesh.

Lattice GirdersLattice girders serve some of the best functions in construction support systems, and offer an economical alternative to other support methods for a wide variety of applications.

Lattice Girders are lightweight, can be handled easily without special equipment and therefore are best suited in slab reinforcement, making it easy to install.

Lattice girders have been tried and tested with great success in numerous operations.

It is used, where concreting is performed in two stages, mainly as reinforcement of prefabricated slabs and beams. The product is manufactured from cold drawn high tensile black deformed or smooth wire.

BRC Mesh Reinforcing

Galvanised Welded MeshGalvanised welded mesh is used in many industry sectors such as agriculture for fencing and enclosures, building and construction for site establishments, meshing and lacing purposes in the mining industry, gabion boxes for retaining walls as well as in the general South African household.

Galvanised welded mesh is produced to the highest standards of quality. Thorough testing of wire strength and aperture size is carried out during all stages of manufacturing.

Galvanised welded mesh is manufactured from galvanised wire(Class A: >260g/m2 and Class C: 40-70g/m2), resistance welded at intersections, allowing the mesh to be cut or bent to any shape as required. This maintains the tensile strength of the wires.

Weldmesh Gabions and MattressesWeldmesh Gabions and Mattresses are manufactured from lightly galvanised (Class C > 100g/m²) wire of 5.6mm diameter (UTS 500 – 700 MPa) and have minimum weld shear strength of 9.3 kN. BRC Mesh offers these options for specific applications.

Wire Spacing

Weldmesh Gabions are produced with 100mm x 100mm wire spacing. For all non-standard gabions it is advisable to contact BRC Mesh for personal attention to specific requirements. Weldmesh Gabions offer a wide variety of uses in all types of hydraulic structures, including:

• Retaining Structures – Retaining walls, revertments, column basis and toe walls to embankments, bridge protection and cuttings.

• Anti-erosion structures – sea walls, riverbank embankments, canal, damn, weirs and reservoirs.

• Landscaping and architectural applications.

BRC’s Gabions and Mattresses can be delivered to site in sub-assembled units together with tying wire or spirals.

Weldmesh Gabions - Assembly & Packing

Step 1: Groundwork of Spirals

• Use the 1.5m Spiral provided and stretch to approximately 35m.

• Cut to the required lenghts but allow an additional 100mm for tying.

Step 2 & 3: Pre-Assembly

• Place panels in their correct positions.

• Attach the base panels by rotating the spiral through the mesh panel openings and secure firmly at the ends.

• Repeat the above step to complete the pre-assembly process.

Step 4 to 7: Final assembly of Weldmesh box/Mattress.

• Bring all panels in a vertical position and use the spirals to secure all panels together by rotating the spiral through the mesh panel openings.

• Ensure that the insert panel is spaced at every meter.

Step 8 & 9: Filling with stones

• Fill up the Weldmesh box/mattress with stones to the top.

• Ensure that all sides of the box/mattress are straight.

• Binding wires may be required to support the insides of the box/mattress.

• Overfill the box/mattress slightly to allow for the stones to settle.

Step 10: Final stage of Assembly

• Close the lid and use the spiral to finally secure all sides.

Bearing Plates (Washers)Bearing plates are used with rock anchor installations to provide a real support and load distribution to the rock surface in the vicinity of the installation. Bearing plates differ in their surface profile, material thickness and size, as well as hole diameter.Flat

Flat bearing plates are simple plates, provided with a hole for the bolt.

Domed

The surface of the plate is pressed into a domed profile. Dome bearing plates are selected for applications where the hole and the rock surface are not at right angles, for example angled holes or uneven rock surface. Used with a spherical seat or a ball-nosed nut the bearing plate is able to articulate under the seat enabling self-alignment and ensuring flush contact with the rock surface.

The hole in the domed bearing plate is therefore necessarily of a greater diameter than the bar diameter. The domed profile also provides greater pull-through strength, enabling the steel content to be optimised.

Ribbed

The surface of ribbed bearing plate is pressed into four ribs, radiating from a domed central portion around the hole.The ribbed profile provides strength and stiffness. Ribbed bearing plates are selected for applications where bolts are installed at right angles to the plane of the rock and where flat rock surfaces are experienced. The hole size provides a loose fit for the bar but does not allow excessive play.

Dog Ear

Most bearing plates are provided with a dog ear corner equipped with a hole. This provides for the suspension of lightweight items such as trailing-cables, vent brattices, etc.

Bearing Plates (Washers)Bearing plates are used with rock anchor installations to providearea support and load distribution to the rock surface in the vicinityof the installation.
